9- Claims. (01.12'84244) My invention relates to a syringe andparticularly relates to a vaginal syringe oi the type adapted for use inirrigating and distending the vagina for .treating irritated anddiseased tissue e therein,

Heretofora sprays have been used wherein the fluid emerging from thenozzle openings impinges directly. upon thesame area which is subjectedto the spray or treatment. This action results in- 10" irritation andeven shock to the subject treated. Since irritation of the area results,the subject must be treated for brief intervals of time to obviateexcessive irritation or shock.

It is an object of my invention-to provide a continuously rotatablespray of fluid to be applied to sensitive surfaces without in anywaycausing irritation or sting to the subject under treatment. Itis, also,van object-of my invention to provide aspray whereby the irrigating fluidmay be ap^ zo plied for a longer period of time because of theelimination of irritation.

A Another object of my invention is to provide a spray of. the type thatmay be easily disassembled for sterilizing purposes and which may beeasily 25 and accurately assembled by a person whether skilled orunskilled in the handling of suchinstruments.

Another object of my invention is to'- construct a syringe that is lightin weight and sturdy i-n- 30% construction.

Another object of my invention is to provide a syringe wherei-nvthefluid lutilized for irrigati-ng: purposes may. also provide a turningmoment upon the rotatablenozzle.

3Q V,Another object of my invention is to provide a guard forpreventing. the sensitive portion of the organ to be sprayed from'contacting the rotatable nozzle of the syringe.-r

Other objects of my invention are to provide 40 an improved device ofthe character described,Y

that is' easily and. veconomically produced ona manufacturing basis,that is' sturdy in construe-- tion, and the efciency of which is veryhigh.`

With the4 abovea'nd related objects inview my invention consists in thedetails of construction and combination of parts as will hereinafter bemore described andV which` will be more readily understood whentliedescription is read W in conjunction with the accompanying drawings;

Referring in greater detail to the drawings, I show in Fig.- l a spraymainly comprised of cast aluminum or other similar low density metal ornon-metallicsubstance that will not rust or corrode, and which rendersthe completed device, light in Weight; the rotatable nozzle, however, iscomprised of non-corrocling metal. The spray comprises a, base portion,generally designated as AY of aluminum. which hasv an inlet passagewayl0 and an outlet or discharge passageway I2 longitudinally therethrough.At one end of the passageway is a hollow cylindrical member or tube I4which has an enlarged outer surface I 6 to receive-,a rubber tube (notshown). A second tube I8, similarly constructed and functioningsimilarly as the-tube I4,. has its opening in alignment withthedischarge passageway I2.

Centrally locatedin the upper central portion of the base A is aterminal opening 20 of a nozzle inlet passage-way 22 that joins theinlet passageway I-Il. The passageways IIL I2" and 22 terminate at oneend in a recess 24, as shown in Fig. 4, located in the upper portion ofthe base A in order that the uid may have a continuous circui-t.LInserted within the base at the central opening is a hollow plug 26,whose opening 28 is aligned with the opening 20 but which iscomparatively restricted in cross sectional area in order to increasethe velocity of the liquid passing that opening.- The plug is conicallyshapedfon its-uppermost surface, as at 3l), so that the portion of thecone 30 extends above a fiat surface 32- forming a portion oftherecess2`4.

A cylindricalA wall 34, integrally formed with the base A, has the inletpassageway I0 terminate in its inner curved wall 36 above the flat`surface 32 of the-recess- 24. The purpose of locating theinletpassageway, as above described, is to have the fluid discharge uponvanes 38 mounted upon arotatable nozz1e,- generally designated B, andhereinafter further described in detail.

A disc-like n'leznlier,y generally designated as C, is mounted with-inthe central recess 24 in the base.- The disc-like member C has a atlower surface 40 which is adapted tol be placed adjacent the flatsurface 32, and the member C, also, has a central aperture 42therethrough. The metal adjacent the aperture 42 is extruded so that thelower surface has a slight recess to t over the cone 3E), and the upperportion is extrude-d as at 44 to serve as a guide bearing or pedestalfor one end 46 of the nozzle. A thin annular rim 48 is formed upon theupper surface of the disc-like member C close to the curved edge.

The rotatable nozzle B, comprised of non-corrosive metal, has a curvedbounding surface 49 and a central passageway 5E] longitudinallyextending from the end opening. A plurality ofl small openings 54 extendthrough the curved bounding surface and the tip 56' of the nozzle.

The small openings 54 permit thej discharge-of;y

the hygienic fluid.

It is to be observed that the'openings 54 are .base 526 and ahollowrcylindrical ange 51 which extends downwardly and is adapted toki'lt into the recess 24 so that the'outside wall of the ange 51 andtheinside curved wall 36, that partially defines the-recess, contact oneanother.' A portion of the inner curved surface of the flange 51 also isengaged by the rim 48 ofthe disc-like member in order to hold thedisc-like member in a denite position, whereby irrigating fluid may passthrough the disc-like member. yA central opening 58 through the basey 56is of a suicient diameter' to permit the rotatable nozzle to rotatefreely therein and in addition the opening allows some of the'dischargedfluid to flow into the discharge passageway.

From the base 56 of the guard D are a'plurality of vertically extendingrails 6B, the corners of which are rounded to prevent the users or theoperators'of the spray from cutting'themselves.-

The rails are merged 'together by the metal 62 at their upper'end, but aslight opening remains.v *The central opening does not permit the bodyof the rotatable nozzle to pass therethrough, but does permit fluid tobe sprayed therethrough. The 'metal vsurrounding the central openingserves as a journal bearing for the nozzle.

A notch10, as illustrat'ed'in Fig. 4, is cut onthe outer curved surfaceof the guard D to cooperate withja'lug 68 positioned to extend radiallyinward of the inner curved surface 36 of`the cylindrical member 34 ofthe upper portion of the baseV A; The purpose of `having an interttinglug and recess is to align the guard D and base A in a predeterminedrelationship whereby an opening 1l in flange 51 will be in alignmentwith the 'terminal opening l0 for iluid to pass therethrough.l Sucharrangement eliminates any possibility of theelements being assembled inany position but the correct position, irrespective of whether theperson isskilled or unskilled in the handling of instruments. 1 Y

A horizontally extending annular ilange 13 is on the base fof the guardto permit a retaining member, generally designated as E, to retain thebase A, and the guard D in aligned relationship. The retaining member Eis comprised of aluminum, and its main body portion 15 isrof an'ellipti- 14,14 on the cylindrical member 34. The continuous passagewaysdescribed serve to guide the spent fluid, that has passed from thenozzle,

to the exhaust outlet.

ments hereinbefore'described will be incorrectly alignedvand'operableposition. l

Located upon the-surface of the guard member and the retainingV memberthat are in engagement are a plurality of vertically extending cut awaysegments forming passageways that terminate in the recess 24. Thepassageways serve as conduits Vto theexhaust outlet for spent iluidvthat has passed from the nozzle.

A recapitulation of the operation of-myinljvention is as fol1ows:- Y Y YvWhen the vdevice is assembled and connected to a source of irrigatingduid under pressure, the

iluidpasses through the inlet passageway I0 and the opening 1I andimpinges upon the Vvanes'SB of thenozzle B thereby rotating the nozzle.A

portion of the fluid'passes to thebranch passage-1 way 22, through therestricted orifice 28, where the velocity of the iluid is increased andApasses directly through the nozzle passageway 50 where the fluid hasegress through the ports or open'- ings 54. The spent fluid may iind itsway back tothe exhaust passageway I2 through the ports 12, 14 and theopening 58 on the guard base'D. Y

When the instrument is disassembled as for purpose ofsterilization, thecoupling Fis un--I screwed by turning the knurled Vportion ofthecoupling; the 'elements A, B, C, D and E then may be separated. Toassemble the instrument, the

intertting lug 64 and slot 66A also aligns the dilator D and theretainer E. :The coupling F is then placed in position and turned untilvthe instrument is held securely in assembled posif-- tion.. 1 j' Atapered extension 90 protrudingrdownwardly from the flat surface of thebase 56 of the guard `D has its edge adapted to engage"V the upper'sid'eofthe Ahub to which the vanes 3 8 are attached.; This extensiongllserves as a journal bearing for l the rotatable nozzle and,Y also,limits the. movement of the nozzle in one direction.

It is, also, within the contemplation of my invention to use hard rubberor bakelite for'various elements of my'spray'. 7
